Semen is a biological fluid that is released by the penis during ejaculation. It contains sperm intended to fertilize an egg as soon as the opportunity arises. But he has many other functions and qualities …
What is sperm made of?
From the Greek sperma (semen), semen actually contains much more than sperm alone. As June Pla explains in her book Club enjoyment, we also find the preseminal fluid (produced by the bulbo-urethral glands), prostatic fluid (produced by the prostate), and seminal fluid (produced by the seminal vesicles). Semen is a mixture of all of that. Spermatozoa represent very little of the total volume (around 1%),
“From a medical point of view, semen does not contain urine or other secretions harmful to health, but it can of course be the vector of an infection”, notes Dr. Descamps, surgeon-urologist (source 1).
Is semen a vector of infections?
Yes. There are more than 30 sexually transmitted infections caused by viruses, bacteria or parasites. Most of them can pass through any mucous membrane: the eyes, throat, mouth or anus.
Does semen smell? a taste ? a color ?
“The taste of semen and its odor vary among men and probably according to their food recent (a bit like milk). It can be sweet, tasteless, while in others the taste is stronger: salty or bitter. However, to date, there is no scientific study on this subject and these impressions emanate from the testimony of each other. », Underlines the urologist (source 1).
Note: the sperm is not not made to smell or taste good. Indeed, as Dr Descamps notes, nature rarely produces unnecessary things. However, when the semen is emitted, the sexual intercourse is generally “consumed”. Unlike sweating and secretions emitted before intercourse (perspiration, love juice, etc.), the sperm would not therefore have the objective of attracting customers, nor of being exciting.
What are the colors of semen?
Semen may be transparent, white, or slightly yellow. Depending on its density, its color will also be more or less intense. If intercourse is frequent, the amount will be less and the color lighter.
In case of change in color of semen, it is recommended to consult. A sperm culture examination allows you to look for the possible presence of bacteria in semen.
If the man can produce sperm every day, the spermatogenesis complete (renewal and complete maturation of sperm) lasts about 64 days. The production of sperm begins at puberty and continues until the end of life.
How long are sperm fertile?
In the vagina, sperm have a lifespan of 2 to 5 days. If we freeze them, they can then be stored for up to 10 years! On the other hand, there are many things that can make them inefficient, such as heat, ultrasound, etc. Based on this observation, several methods of male contraception are now emerging.
Is semen good for you?
Already, Cleopatra would have been seminophagus (editor’s note: relating to swallowing semen) in order to benefit from the curative effects of the substance. As for the Romans, they attributed to this seed longevity properties. According to legend, Empress Messaline was smeared with sperm from young adolescents who masturbated on her (source 1). Today, we find this practice in pornos under the name of “Bukkake” which means “splash” in Japanese. So what about the benefits of this mythical substance?
Does it have antidepressant effects?
According to some studies, this liquid has natural properties acting as an antidepressant (source 2). He would free serotonin and some melatonin, two hormones known to calm anxiety. Direct contact with the sperm through any orifice would therefore make it possible to fight against blues. More seriously: as we know, innumerable elements come into play in the feeling of sexual intercourse. The love and trust that we have (or not) towards our partner; our psychological and physical state; etc. All of this will greatly promote or disrupt the production of feel-good hormones.
A nutritious seed
The semen would contain proteins, vitamins (C and B12), and would also be potentially rich in minerals (potassium or magnesium). Yum-yum.
Does it make you fat? No. A teaspoonful of the seed “contains 5 to 25 calories, or between 4 radishes and 100 grams of cauliflower. Normally, it shouldn’t weigh too much on the stomach. Protein level, on the other hand, it is rather not bad, since one finds there the equivalent of an egg white ”, affirms this Neon Mag ticket.
Positive effects for skin and hair?
Scientists from the University of Graz in Austria, Tobias Eisenberg and Frank Madeo, have claimed that a molecule contained in semen: the spermidine is an excellent Anti aging. The seed would be good both for the beauty of skin and hair.
As June Pla recalls in her book: “Just because it is supposedly good for the health does not mean that people are ready to eat cod liver oil or brush themselves with slime. Burgundy snails. »So no need to arrive with big hooves, a smirk and this article in hand to convince your other half of the merits of spermatophagy
Do we get along well, we judge the fertile sperm quality and not its taste quality for example, even if it is a safe bet that the two are linked. ” The spermogram is the basic exam in exploring themale infertility », Explains urological surgeon Fabien Descamps. To do this, we will analyze the spermatozoa from different angles: are they numerous, mobile, alive?
This test must take place after three days of abstinence and the standards vary between laboratories, but the “normal” volume of amount of semen emitted during ejaculation would be between 1.5 and 6 ml (like between a small and a large teaspoonful). According to the new standards of the WHO, the World Health Organization (May 2010), the normal count of sperm in ejaculation is greater than 15 million / ml and greater than 39 million by the totality of ejaculation. So much for the quantity.
We will also make sure that they have a good vitality (a majority of living), and that they move (a majority in shifting). But beware: many scientists agree that there can be large variations in these values in the same patient over time and for a variety of reasons. The clinical relevance of these results is therefore variable.
- Keep your testicles cool : as we know, to be effective, spermatozoa must have a body temperature 2 ° C lower. For those who want to design, saunas, hammams and jacuzzis are therefore not great friends. Like everything that can disturb the natural regulation in that place: clothes that are too tight, wearable in your pocket at all times (possible endocrine disruptors as a bonus), etc.
- Eat healthy : “We must focus on foods rich in antioxidants such as green vegetables, fruits, vegetable oils, nuts, green tea, dark chocolate and spices (curry, turmeric, ginger). These foods protect you from external aggressions such as pollution, stress, UV rays or tobacco. It is also advisable to consume foods rich in magnesium, vitamin B9, selenium and zinc, as well as thoserich in omega-3such as walnuts and walnut oil, fatty fish (salmon, herring, anchovies), rapeseed and soybeans ”, explains the Procrea site, a group of cutting-edge medical establishments, made up of a team of fertility experts (source 3).
- Take care of the hygiene of life in general: as in most areas, a healthy lifestyle has a remarkable influence on sperm quality. Thus, the lack of sleep, the consumption of tobacco, alcohol or other types of drugs, or even being overweight can affect the quality of sperm.
Is it possible to stop / not producing sperm?
Urological surgeon Dr Sébastien Beley explains in an interview that a lack of sperm production can be aandropause gene or prostate aging and be related to age, but also simply caused by a large prostate, which will compress the ejaculatory ducts which will then generate less sperm.
Is semen sexually important?
Dr Descamps conducted a study on this topic with a small panel of people and it led him to the following conclusion: “Without sperm, whatever the reason, then something will be missing, to one and / or the other … ”(source 1). Nevertheless, he recalls that it depends on cultures, ethnicities, times, etc., and that we can very well have a fulfilling sexuality without ejaculating sperm in quantity, or even without ejaculating at all.
In conclusion: sperm is both a vector of life (pregnancy), death (sexually transmitted infections), problems (poor quality of sperm), and, sometimes, eroticism (possible sexual games). It has its strengths and weaknesses, the important thing is to know them well in order to do things conscientiously. Especially for men, but also for women!
